[Tretyakov Rostyslav]

Michail_David:

谢谢你，维塔利。但在ExtTempBuffer[i]=NormalizeDouble((close[i]-open[i])/Point(),2);这一行，我仍然得到一个错误。

1.检查索引。

   SetIndexBuffer(2,ExtTempBuffer);
   SetIndexBuffer(2,ExtPriceBuffer);

2.为什么你需要这2个缓冲区

      ExtTempBuffer[i] = NormalizeDouble((close[i]-open[i])/Point(),2);
      ExtPriceBuffer[i] = NormalizeDouble((close[i+1]-open[i+1])/Point(),2);

如果

 ExtPriceBuffer[i] = ExtTempBuffer[i+1]

[Tretyakov Rostyslav]

Michail_David:

在ExtTempBuffer[i]=NormalizeDouble((close[i]-open[i])/Point(),2);这一行给出了一个错误，因为元素[i}。

你好！有一个基于iExposure.mq4指标的修改后的指标"iexposuregmini.mq4 "内置于终端。请您告知如何将信息员的位置（窗口）移动到图表窗口的左下角？而在从图表中删除指标后，指标栏仍然...如何才能解决这个问题？我事先非常感谢!

[Michail_David]

MakarFX:

1.检查指数

2.为什么需要这两个缓冲区？

用一个缓冲区ExtTempBuffer[i]=ExtTempBuffer[i+1]没有成功，决定这样试试，但也没有成功。

接住

谢谢你，马克。测试时在同一行又出现同样的错误。这在任何方面都是无效的。

这就是2020.11.03 23:38:19.815 2020.07.10 16:10:00 MSBB EURUSD,M5: array out of range in 'MSBB.mq4' (78,20)

这就是它所说的 2020.11.03 23:38:19.815 2020.07.10 16:10:00 MSBB EURUSD,M5: array out of range in 'MSBB.mq4' (78,20)

我没有得到任何错误，但日志是巨大的，因为

Print ("ExtSignalBuffer = ", ExtSignalBuffer[i]);

[Michail_David]

MakarFX:

我没有得到任何错误，但日志却很大，因为

对，一样。我似乎没有考虑到所有的条件。在信号价值上，许多人是巨大的。谢谢你的帮助。我将继续关注这些情况。

[IndependentMK]

Александр:

它没有打开，因为其中一个条件没有得到满足。

它是

或这个

评出两个闪光点//，你就知道是哪一个了。这就是你发现错误的方法。

谢谢亚历山大!
